Polished Concrete Fire Surround and Hearth

We need a new fireplace hearth and would like to source one in a polished concrete. Googling has, so far, turned up very little.

"polished concrete" turned up

• The Concrete Society @ www.concrete.org.uk - Their supplier directory was not very usefull and the only links I could find were to large suppliers of concrete.
  
• Paul Davies Design @ www.pauldaviesdesign.co.uk - All seems very grey
• SOI source @ www.soisource.com - Silly flash based site, with very little content about what they do.
  

Noticed this in an add in the back of Elle Decoration...

• Lowinfo Design - www.lowinfo.com - Again all very grey.

We are really looking for a product that has some colour and with the agregate exposed.

Why?

This blog is a place for me to record the searches I do while looking for products to buy.

I find del.icio.us usefull, and use it a lot, but one thing it doesn't do is allow me to record my progress as I try out new search terms and refine them over the search process.
